One end of the close reference line X of subsegment 311 is the first end 3111, one end away from reference line X is the second end 3112, first
Minimum range between top edge and tubular wine wheel 1 periphery wall of end 3111 is H1 (as shown in Figure 9), the second end 3112
Top edge and tubular wine wheel 1 periphery wall between minimum range be H2 (as shown in Figure 10), H1 be more than H2.Thus may be used
So that the top edge of one end away from reference line of each snail tongue section 311 (the second end 3112) and tubular wine wheel 1 periphery
Minimum range between wall less than the one end (the first end 3111) near reference line top edge and tubular wine wheel 1 periphery wall it
Between minimum range.
Owing to, on the axis direction along tubular wine wheel 1, tubular wine wheel 1 air-flow is small in ends, middle maximum, from middle toward two
End is sequentially reduced (as shown by the arrows in Figure 4), and the distance between snail tongue and tubular wine wheel 1 is less, the pressure of air-flow at snail tongue
(negative pressure) is the biggest by force, and the air of suction is the most more, and the speed of air-flow is bigger.Therefore, by the first snail tongue section 31a and
